Containing over ∼1057∼1057 baryons, neutron stars (NSs) are gigantic nuclei rich in neutrons. With masses on the order of solar mass 𝑀⊙≈1.99×1030M⊙≈1.99×1030 kg and radii around 10 km, neutron stars are compact objects of extreme densities. Their compactness 𝐶=𝐺𝑀/𝑅...
Neutron stars are highly dense remnants of massive stars that have collapsed, composed mainly of neutrons and other elementary particles. They are observable due to their strong magnetism, rapid rotation, and emission of radio radiation in a narrow cone. ...
Although\(n-n'\)transition is suppressed for neutrons bound in nuclei by nuclear forces, it can be effective in neutron stars (NS) where the neutrons are bound by gravity. The transformation of neutrons into mirror neutrons should decrease the degeneracy pressure, thereby softening the equation o...
1 INTRODUCTIONSystems of interacting fermions are in superuid phases at low enough temperatures. Thus the core and inner crust regionsof neutron stars consist mainly of superuid neutrons. The neutron superuid in the core, carrying the bulk of the mass andmoment of inertia of the star, is the...
Although n − n transition is suppressed for neutrons bound in nuclei by nuclear forces, it can be effective in neutron stars (NS) where the neutrons are bound by grav- ity. The transformation of neutrons into mirror neutrons should decrease the degeneracy pressure, thereby softening the ...
Its measured lifetime depends on the orientation of the two particles and is on the order of 10−10–10−7 second, in agreement with that computed from Dirac’s theory. The Dirac wave equation also describes the behaviour of both protons and neutrons and thus predicts the existence of ...
the pulse duration of the gamma-driven neutrons is much shorter52,53due to the relativistic feature of the electron beam generatingγ-rays. Nowadays, the high-yield laser-drivenγand neutron-beam production schemes are based on applications of high-intensity multi-petawatt-class laser systems, wher...
of the lightest elements - lithium, helium and beryllium - completely contradict this conception." These isotopes consist of a compact nuclear core and a cloud made of diluted nuclear material - called 'heiligenschein' or 'halo'. A halo consists mostly of neutrons that are very weakly bound ...
As the neutron lifetime puzzle continues haunting the community, one shall not overlook where neutrons abound. Containing over ∼1057 baryons, neutron stars (NSs) are gigantic nuclei rich in neutrons. With masses on the order of solar mass 𝑀⊙≈1.99×1030 kg and radii around 10 km, neut...
Despite the notion, cool neutron stars accommodate, in the crust, various nuclei immersed in a degenerate electron-muon environment (maybe as “pasta” or “spaghetti” or crystalline medium). In the deeper interior, above the neutron drip density, neutrons and light clusters begin to dominate ...
